River distribution of Shili River

The Shili River in Zuoyun County, Shanxi Province, "the vein of the county and city comes from the northwest, Hailongye." In ancient times, it was called Wuzhou River. It originates from the ravines of Yuquan hills in the south and north of Zuoyun County. Before 1978, there were gurgling mountain springs in many ravines in Madaotou Township in the south of Zuoyun County, flowing north into the Shilihe Reservoir in the west of the county; 15 kilometers north of the city, there is a Monk Mau with an altitude of 1,965 meters. The mountain stream stone to the south of it In the cracks, there are also more than ten mountain springs trickling out and flowing southward into the Shili River. The source of Shili River is composed of groups of mountain springs. The northernmost tributary originates from Liangcheng, Inner Mongolia, and the westernmost one originates from Youyu. Shanxi is a region rich in groundwater. Of course, the larger water source of Shili River is composed of surface water. During the flood season of July, August and September every year, the floods of Shili River are huge and magnificent. According to hydrological records, the runoff during the flood season in 1959 reached 1 billion cubic meters, so Shili River is a typical seasonal river.

When did the name Shili River come from? Judging from modern readings, it was used in modern times. Starting from the source of Zuoyun River, the Shili River flows eastward with hundreds of twists and turns. It enters the southern suburbs from Jiudaoshan, passes through Gaoshan Town and Yungang Town, exits the mountain in the west of Xiaozhan Village, Majunying Township, and circulates 10 kilometers south to the east of Tiancun. It merges into Yuhe River and becomes Hehe River, which flows into Sanggan River with a total length of 89 kilometers. The river bed width is 150-400 meters, the drainage area is 2,000 square kilometers, and the average annual runoff is 40 million cubic meters. Because the river goes out of the small station ten miles to Nanyang and ten miles to the southeast, and the river is ten miles away from Datong City, it is called Shili River. The Shili River Basin in Yuxi City, Yunnan Province is located in Xinping County, Yuxi City, Yunnan Province. It is a first-class tributary on the right bank of the Gasa River. The basin area is 50.1 square kilometers, the river length is 14.05km, the natural drop is 1900m, the average river channel drop is 12.16%, and the average elevation of the basin is 2160 rice. Jiasa River belongs to the Yuanjiang River system in the Red River Basin.

The Shili River Basin originates from the Ailao Mountain National Forest Reserve with an altitude of more than 2,700m. The coverage rate in the basin reaches 80%, with abundant water, sufficient and stable runoff supply, large river bed ratio drop, and good conditions. Terrain conditions for water energy cascade development. There are no industrial or mining enterprises in the basin, the water quality is clean and pollution-free, there is less water consumption for farmland irrigation and drinking water, and the impact of human activities in the basin is small. According to estimates, the theoretical water energy reserve in the Shili River Basin is 21,000 KW, and the developable installed capacity is about 19,000 KW.

The Shili River Basin Water Energy Resources Development Plan is a professional plan to study the development of hydropower resources in the basin. Its main task is to identify the water energy resources contained in the river, and according to the national economic and social development, each Based on the growing demand for electricity from departments and local governments, combined with the actual conditions of the river basin, development conditions and technical and economic characteristics, we will formulate and select development and utilization methods, formulate cascade construction and rationally arrange development procedures, and recommend development and construction projects. The task of developing water energy resources in the Shili River Basin is mainly hydropower generation.
